1 Corinthians 6:12-20 - Avoid Sexual Immorality
12 "All things are lawful for me," but not all things are expedient. "All things are lawful for me," but I will not be brought under the power of anything. 13 "Foods for the belly, and the belly for foods," but God will bring to nothing both it and them. But the body is not for sexual immorality, but for the Lord; and the Lord for the body. 14 Now God raised up the Lord, and will also raise us up by his power. 15 Do you not know that your bodies are members of Christ? Shall I then take the members of Christ, and make them members of a prostitute? May it never be. 16 Or do you not know that he who is joined to a prostitute is one body? For, "The two," says he, "will become one flesh." 17 But he who is joined to the Lord is one spirit.
18 Flee sexual immorality. "Every sin that a man does is outside the body," but he who commits sexual immorality sins against his own body. 19 Or do you not know that your body is a temple of the Holy Spirit which is in you, which you have from God? You are not your own, 20 for you were bought with a price. Therefore glorify God in your body.
